Edit course profile button to course overview page

[TillMeineke]

the button would be really helpful on the overview page (https://courses.datatalks.club)

Currently it's on per-course basis - just like on Kaggle people can have different names in different competitions

But probably it'd be helpful to have a slightly different setup - one common profile and different instances for each of the course that inherit some common attributes (links, name, etc)

we had this discussion on slack. It was just an idea for improvement.
